场景2---循环中的内部函数
    function TestObj(name) {
        this.name = name;
    }
    var objs = [];
    var obj;
    function test() {
        for (var i = 0; i < 100; i++) {
            var name = "张磊" + i;
            obj = new TestObj(name);
            obj.printName = function () {
                    console.log(obj.name);
                }
            objs.push(obj);
        }
    }
    //外部函数执行，闭包形成。内部函数obj.printName中的obj全部指向最后一次new TestObj(name);
    test();
    //所以这里会输出100次-----"张磊99"
    for (var i in objs) {
        objs[i].printName();
    }
解决办法
    function TestObj(name) {
        this.name = name;
    }
    var objs = [];
    var obj;
    function test() {
        for (var i = 0; i < 100; i++) {
            var name = "张磊" + i;
            obj = new TestObj(name);
              (function (target) {
